Engineers designing a braking system for an electric car want  to test the current that the system generates. They drive a car which is fitted with this braking system at different speeds, brake,then measure the voltage generated.

Engineers designing a braking system for an electric car want  to test the current that the system generates. They drive a car which is fitted with this braking system at different speeds, brake,then measure the voltage generated.Identify the independent and dependent variables in this experiment.Formulate a research question.Predict a suitable hypothesis for the experiment supported by scientific reasoning.

The engineers who conducted this experiemnt formulated a hypothesis that the voltage generated by the braking system would be directly proportional to the speed at which the car is travelling.Determine whether their hypothesis was correct or not.Support your answer with the data.B

A new design for the braking system on a certain type ofcar has been proposed. For the current system, the trueaverage braking distance at 40 mph under specified con-ditions is known to be 120 ft. It is proposed that the newdesign be implemented only if sample data stronglyindicates a reduction in true average braking distance forthe new design.a. Define the parameter of interest and state the relevanthypotheses.b. Suppose braking distance for the new system isnormally distributed with s 5 10. Let X denote thesample average braking distance for a randomsample of 36 observations. Which values of x aremore contradictory to H0 than 117.2, what is theP-value in this case, and what conclusion is appro-priate if a 5 .10?

Using what you know about friction and other forces, explain the effect of the variable you tested on braking distance.

What is the science behind brakes? What do they really do?
